In order to run the application when not using the "full" bundle, you must have a Java Development Kit (JDK) installed.
The recommended version is JDK 11.
On Linux, to install OpenJDK, use
sudo apt install openjdk-11-jdk. In general, you find good binary builds
for all platforms on adoptopenjdk.net.
For real-time sound reproduction, the SuperCollider server is needed. The recommended version is 3.10.0 or above (technically 3.7.0 or higher should work).
When using JDK 8 under Debian and GNOME, there is a bug in the assistive technology (Atk) which results in
performance degradation over time, as the some of the UI is used. To solve this problem, create a plain text file
~/.accessibility.properties (that is, in your home directory) and put the following contents inside:
Mellite has now also been tested with JDK 11. You will see some warnings/errors when starting, including "An illegal reflective access operation has occurred" and "ERROR com.alee.utils.ProprietaryUtils - java.lang.NoSuchFieldException: AA_TEXT_PROPERTY_KEY". These are related to the Web Look-and-Feel, and can be ignored. However, JavaFX is not available as a system-wide package for JDK 11, so the API browser currently does not work under JDK 11.
The standalone jar, created via
./sbt mellite-app/assembly produces
app/Mellite.jar which is double-clickable and can be run via:
$ java -jar app/Mellite.jar
Runnable packages can be created via
./sbt mellite-app/universal:packageBin (all platforms) or
./sbt mellite-app/debian:packageBin (Debian).
Video and text tutorials, as well as API docs can be found online here: www.sciss.de/mellite
Note that this project is still experimental in its nature, meaning that many features are incomplete or buggy, and that the application is subject to change. For example, there is no guarantee that workspaces in an older version of Mellite can still be fully opened in newer versions, although I try to minimise incompatibilities in the serialization. You have been warned!

If you want to use Mellite as a "library" in your project, you can link to a Maven artifact.
The following artifact is available from Maven Central:
"de.sciss" %% "mellite-core" % "3.4.0" "de.sciss" %% "mellite-app" % "3.4.0"
See the section 'download and installation' for requirements (JDK, JavaFX).
Mellite builds with sbt and Scala 2.13, 2.12. The last version to support Scala 2.11 is 2.38.1. The last version to support Scala 2.10 is 2.10.2. The default target and the binary distribution of the application are currently based on Scala 2.13. Scala 2.12 was used up to Mellite v2.43.0.
The dependencies will be downloaded automatically from Maven Central repository, except for snapshots during development.
Dependencies not found are all available from their respective
git repositories, so in case you want to build a snapshot version, you
may need to check out these projects and publish them yourself using
See section 'running' for ways of building and installing standalone bundles.
We are currently experimenting with a build variant that bundles the JDK using the JLink plugin for sbt-native-packager.
In order to build this version, run
sbt mellite-full/universal:packageBin. This must be done on a host JDK 11.
The produced installation is platform dependent, so will create a version that only works on the OS you are building from.
Note that should probably specify an explicit java-home, otherwise the bundled package might be unreasonably large:
sbt ++2.13.3 -java-home ~/Downloads/OpenJDK11U-jdk_x64_linux_hotspot_11.0.9_11/jdk-11.0.9+11 clean update mellite-full/debian:packageBin
This section is an aide-mémoire for me in releasing stable versions.

We're currently publishing the following artifacts:
To build for Linux:
sbt -java-home '/home/hhrutz/Downloads/OpenJDK11U-jdk_x64_linux_hotspot_11.0.9_11/jdk-11.0.9+11' mellite-full/universal:packageBin mellite-full/debian:packageBin
Copy the artifacts to a safe location now. To build for Mac and Windows, we need to publish all libraries now to Maven Central (use JDK 8 again!). Then Windows can be built on Linux using wine:
rm -rf full/target(otherwise Jlink fails)
Z:\home\hhrutz\Downloads\OpenJDK11U-jdk_x64_windows_hotspot_11.0.9_11\jdk-11.0.9+11\bin\java.exe -jar Z:\home\hhrutz\Downloads\sbt-1.4.2\sbt\bin\sbt-launch.jarthen in sbt console:
N.B.: sbt 1.4.x seems no longer to work under wine due to coursier updates; for now we can still build by setting the version in
build.properties to 1.3.13 temporarily!
For Mac we need a bloody fruit company machine:
git fetch; git merge origin/work
./sbt -java-home /Users/naya/Downloads/jdk-11.0.9+11/Contents/Home clean update mellite-full/universal:packageBin
chmod a+x mellite-full_<version>_mac_x64/bin/mellitethen
